DRAFT-RIGGING.

Specification of Lettersll atent.

Patented Nov. 16, 1915.

Application filed June 12, 1911. Serial No. 632,695.

'To all whom it may concern I Be it known that I, STACY B. HASELTINE, a citizen of'the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Draft-Rigging, of which the following is a specification.

This invention relates to an improvement in means for connecting the ordinary coupler with the ordinary draft rigging employed in railway cars.

The invention consists in providing a-connecting head adapted to receive the end of the coupler and be secured thereto by means of the usual fiat key, with means for receiving and holding a detachable U-shaped band or yoke of metal inclosing the friction or other regulating draft device. And the invention further consists in the novel arts, devices and combinations of parts an de vices hereinafter claimed.

In the accompanying drawing which forms a part of this specification, Figiire 1.

isa side elevation, partly in section, and Fig. 2 is a plan view of the coupler and the means for uniting the same with the draft rigging. Fig. 3 is a section on line 3"3 of Fig. 1. Fig. 4 is an enlarged detail view of the gib or hook on the end of the yoke. Fig. 5 is an enlarged view of a part of Fig. 2.

In said drawing, A represents an ordinary coupler and B the key for securing the same to the draft yoke. I

C is the head of the draft yoke, secured to the coupler by the said key B.

D'represents any ordinary shock absorber or draft regulating device, such as is commonly employed in conjunction with car couplers. E is the front follower of said draft device and F the rear follower thereof.

K, K are the side draftcastings carrying the follower stops against which the fol at its two free ends a turn or gib H to engage in curvilinear slots formed in the head C, the walls of which'slots form stops J, J,

J J The gibs are bent outward from each other and should preferably be bent in rounded form, as indicated in Fig. 5, to avoid putting strains in the metal and to preserve the strength thereof. The head 0 is made in the form of a continuous band to surround the coupler, and leave at the upper sides thereof room for the snug insertion of the yoke G.

The parts are assembled by inserting the yoke G, carrying the draft regulating devices in the head or band C, the gibs I-I entering between the stops J and the counterstops J of the said head. The conpler is then placed in the head and locked thereto by the key B which passes laterally through the head, the coupler and the car sills L L. This means. for connecting the coupler with the draft regulating devices is applicable to any ordinary coupler and any of the ordinary well known friction or other shock absorbing draft gears, is cheap, durable and relatively light for its strength.

I prefer to make the U-shaped yoke of wrought iron on account of its superior strength and flexibility, and also incidentally because it is cheaper than cast steel. The -form is one which lends itself readily to being forged into shape without loss of strength, and when finished may be readily inserted in the head C by flexing the two free ends to pass them within said head, permitting them to spring out into engagement when in place. though it will be understood that the resiliency of the band is not at all relied upon to maintain the engagement of its ends .or gibs with the head; be cause when the coupler is inserted within and keyed to the head, it entirely fills the space so that there can be no subsequent escape'of the yoke from its engagement with the head. as will be understood by reference to Figs. 3 and 4.

The purpose of the curved slots formed in the head U is so that there may be a lateral coupler to move laterally to a certain extent without putting strain upon the shock ahsorhing craft devices or causing them to bind in their operation. One of the special advantages of this method of connecting the coupler with vthe shock absorbingdraft dej the car; and may be applied to,the 'car by simply reversing this operation and without the necessity of distributing the draft rigging or other parts.

Although i have herein used. the terms head and yoke to describe the members C and G, respectively, various other terms may be employed to aptly describe the same. For instance, those skilled in the art may call the member C a hood, or coupler pocket; and the yoke G may be designated as a loop U-shaped strap, or yoke strap.

I claim a 1. The combination with shock absorbing draft devices, of a U-shaped yoke having integral attaching means at its two free ends, a head to which said free ends are attachable, a coupler to which said' head is keyed, and a key uniting said head and coupler, said yoke being readily detachable from the head when the key and coupler are removed, substantially'as specified.

2. The combination of the coupler, the band-like head surrounding the same and provided with stops and counterstops, of the shock absorbing draft devices, the U shaped band or yoke surrounding said shock absorbing draft devices and having at its free ends the gibs for engaging the stops and counter-stops in said head. the free ends of said yoke being passed within the head between it and the coupler when assembled, substantially as specified. j

3. In combination, a Ushaped yoke having outwardly turned, curvilinear gibs forn'ied on the free ends of the arms thereof, a coupler, and means for connecting the coupler and voke,'said means including a. head having curvilinear slots in which are adapted to take the curvilinear gibs formed on the ends of the arms of the yoke, the walls of said curvilinear slots forming stops for said gibs, and said slots and gibs being so formed as to allow the coupler to swing laterally relatively to the yoke.

' 4. In combination, a U-shaped yokehav- 'ing gibs formed onthe free ends of the arms thereofia coupler, a rectangular head having slots therein'within which said gibs are adapted vto take, and means for detachablv securing said coupler and head together, the arms ofthe yoke being detachswingingly mounted on the forwardend of Said yoke. I

6. In a draft rigging for cars, the combination with the yoke, of a draw bar hood 'swingingly mounted onand constructed to receive the forward end of the yoke, the diameter of the hood being greater than the width of the yoke, whereby the hood may swing, and the yoke act as an abutment to limit the swinging movement ofthe hood.
